Forum of Mathematics, Sigma《西格玛数学论坛》（一年1卷）. Forum of Mathematics, Sigma is the open access alternative to the leading specialist mathematics journals. Editorial decisions are made by dedicated clusters of editors concentrated in the following areas: foundations of mathematics, discrete mathematics, algebra, number theory, algebraic and complex geometry, differential geometry and geometric analysis, topology, analysis, probability, differential equations, computational mathematics, applied analysis, mathematical physics, and theoretical computer science. This classification exists to aid the peer review process. Contributions which do not neatly fit within these categories are still welcome.

Evolution Equations and Control Theory《演化方程与控制理论》（双月刊）. Evolution Equations and Control Theory (EECT) is primarily devoted to papers on analysis and control of infinite dimensional systems with emphasis on applications to PDEs and FDEs. Topics include: Modeling of physical systems as infinite-dimensional processes; Direct problems such as existence, regularity and well-posedness; Stability, long-time behavior and associated dynamical attractors; Indirect problems such as exact controllability, reachability theory and inverse problems; Optimization - including shape optimization - optimal control, game theory and calculus of variations; Well-posedness, stability and control of coupled systems with an interface. Free boundary problems and problems with moving interface(s); Applications of the theory to physics, chemistry, engineering, economics, medicine and biology.

European Journal of Applied Mathematics《欧洲应用数学杂志》（双月刊）. Since 2008 EJAM surveys have been expanded to cover Applied and Industrial Mathematics. Coverage of the journal has been strengthened in probabilistic applications, while still focusing on those areas of applied mathematics inspired by real-world applications, and at the same time fostering the development of theoretical methods with a broad range of applicability. Survey papers contain reviews of emerging areas of mathematics, either in core areas or with relevance to users in industry and other disciplines. Research papers may be in any area of applied mathematics, with special emphasis on new mathematical ideas, relevant to modelling and analysis in modern science and technology, and the development of interesting mathematical methods of wide applicability.

ESAIM: Mathematical Modelling and Numerical Analysis《欧洲应用数学和工业数学辑：数学建模与数值分析》（双月刊）. The journal publishes original research papers of high scientific quality in two areas: Mathematical Modelling, and Numerical Analysis. Mathematical Modelling comprises the development and study — e.g. structure, well-posedness, solution properties — of a mathematical formulation of a problem (or class of problems). Numerical Analysis comprises the formulation and study — e.g. stability, convergence, computational complexity — of a numerical approximation or solution approach to a mathematically formulated problem (or class of problems).

ESAIM: Control, Optimisation and Calculus of Variations《欧洲应用数学与工业数学辑：控制、最优化及变分法》（一年1卷）. ESAIM: COCV strives to publish rapidly and efficiently papers and surveys in the areas of Control, Optimisation and Calculus of Variations. Articles may be theoretical, computational, or both, and they will cover contemporary subjects with impact in forefront technology, biosciences, materials science, computer vision, continuum physics, decision sciences and other allied disciplines.

Ergodic Theory and Dynamical Systems《遍历理论与动力系统》（月刊）. Ergodic Theory and Dynamical Systems focuses on a rich variety of research areas which, although diverse, employ a variety of dynamical methods. The journal provides a focus for this important and flourishing area of mathematics and brings together major contributions in the field. The journal acts as a forum for central problems of dynamical systems and of interactions of dynamical systems with numerous other areas, including geometry, geometric group theory, number theory, combinatorics, harmonic analysis, operator algebras, celestial and statistical mechanics, and probability theory.

Electronic Transactions on Numerical Analysis《数值分析电子会报》（不定期）. The Electronic Transactions on Numerical Analysis (ETNA) is an electronic journal for the publication of significant new developments in numerical analysis and scientific computing. Papers of the highest quality that deal with the development and analysis of numerical methods, including rigorous studies of the convergence of algorithms, their accuracy, stability, and complexity. Numerical methods for the solution of continuous models as well as papers in numerical linear algebra are appropriate for ETNA, as are papers of similar quality that discuss implementation and performance of such algorithms.

Electronic Journal of Qualitative Theory of Differential Equations《微分方程定性理论电子期刊》（不定期）. The Electronic Journal of Qualitative Theory of Differential Equations (EJQTDE) is a completely open access journal dedicated to bringing you high quality papers on the qualitative theory of differential equations. All topics related to the qualitative theory (stability, periodicity, boundedness, etc.) of differential equations (ODEs, PDEs, integral equations, functional differential equations, etc.) and their applications will be considered for publication.

Electronic Journal of Differential Equations《微分方程电子杂志》（不定期）. Since its foundation in 1993, this e-journal has been dedicated to the rapid dissemination of high quality research in mathematics. It has ISSN number 1072-6691, and its articles are indexed by Math Reviews, Zentralblatt für Mathematik, and Thomson Reuters web of knowledge.

The Electronic Journal of Combinatorics《组合数学电子期刊》（季刊）. The Electronic Journal of Combinatorics (E-JC) is a fully-refereed electronic journal with very high standards, publishing papers of substantial content and interest in all branches of discrete mathematics, including combinatorics, graph theory, and algorithms for combinatorial problems.
